The Gallium Melting-Point Standard: Its Role in Our Temperature Measurement System
Keyword(s):
Abstract The latest internationally-adopted temperature scale, the International Practical Temperature Scale of 1968 (amended edition of 1975), is discussed in some detail and a brief description is given of its evolution. The melting point of high-purity gallium (stated to be at least 99.99999 % pure) as a secondary temperature reference point is evaluated. I believe that this melting-point tem-perature of gallium should be adopted by the various medical professional societies and voluntary standards groups as the reaction temperature for enzyme reference methods in clinical enzymology. Gallium melting-point cells are available at the National Bureau of Standards as Standard Reference Material No. 1968.
